◉ Flux Processing
It removes impurities on the iron surface, removes zinc oxides on the
skin plating water surface, and prevents the product surface from oxidizing.
The temperature takes about 80℃ to 5 minutes.

→ Month1,000Ton per 300~500kg additional
→ Month1,000Ton In production approximately 300~600kg
→ Month1,000Ton In production approximately 400~600kg
→ Month1,000Ton In production approximately 500~700kg
Provided, That at this time, the concentration of flux is maintained when supplementing water is injected due to consumption of liquid (Zinc Chloride ammonia)
- Conditions for Flux
→ Temperature : 65~75℃
→ Composition: Ratio of weight of zinc chloride and
ammonium chloride (approximately1:1.17)
→ Concentration : 15~40Be°
Excessive iron content increases the effectiveness of the
dross and the penetrator decreases.
- The increase in chloride ions is associated with a decrease in pH
because it means the inflow of acid.
- When the ash is not easily removed from the cooling tank, sprinkle
ammonium chloride at a rate of approximately 120kg per ton of plating.
- There is a unique smell of its own, but the smell of the surfactant
itself does not have a significant impact on the human body.
* Maintain surface tension at 30dyne/cm
- Add NT5181-3g/L to the Fluxtank.
- Flxu : ZnCl₂, NH₄ solution 사용.
- Add NT-518 in case of Zn bounce during melting plating.
* Use pH 4.0 to 6.0
- Maintain pH between 4.0 and 6.0 using ammonia water.
- If the pH reaches 2.0, we recommend a reconstruction bath.
* 1.0% Fe (keep below 10g/L)
- When Fe concentration exceeds 1.0%
Splashing may occur in the molten galvanized tank.
